MEANS FOR 'DEODORI ZING AND SWEET ENING BREAD IN OVENS.

SPECIFICATION forming part of Letters Patent N 0. 523,846, dated July 31, 1894. Application filed June 21,1893. Serial in. 478,325. (No specimens.) 1

To all whom it may concern.-

Be it known that I, MATTHIAS ZOELLER, of the city of Baltimore and State of Maryland, have invented certain Improvements in Means for Deodorizing and Sweetening Bread in Ovens, of which the following is a specification. I

This invention relates to means whereby bread, in baking, is purified or robbed of odor or taste resulting from the absorption of gases from the fuel used in heating the oven, or from the yeast contained in the bread, and it consists in an open box having an inlet and an outlet pipe leading from the same to the exterior of the oven, the said pipes being provided with removable caps and the outlet pipe with a float where the height of the contents of the box and the pipes is ascertained.

It also relates to the method of purifying the bread, as will hereinafter fully appear.

In the further description of the said inven tion which follows, reference is made to the accompanying drawings forming a part hereof and in which--- Figure l is a sectional plan of an oven pro- 7 vided with the invention, and Fig. 2 a section of Fig. 1 taken on the dotted line w-x. Fig. 3 is a section of Fig. 1 taken on the dotted line 'yy. Figs. 4, 5, 6 and 7 are enlarged details of the invention.

Referring to the drawings, A is an oven of the description generally used in bake-houses, and B the furnace having the grate bars, ct.

O O are the flues leading to the chimney not shown.

D is a box partially built in one of the side walls of the oven. This box has an opening I) and is provided with the inlet and the outlet pipes, E and F, respectively, leading pref-' erably to the front of the oven. Both pipes E and F have removable caps c and the outthe same as given. The vapor arising from the contents of the box has the effect of neutralizing the gases in the oven and sweetening the bread, particularly removing the odor and taste of the contained yeast.

When the box D is charged, the caps c are placed on the pipes E and F and nothing further is necessary or hasto be done, until the liquid in the box is exhausted which exhaustion requires a considerable length of time. W hen, however it is exhausted, the box is again supplied with more liquid and the contained solids if solids are employed with the liquid.

I claim as my invention- 1. In combination with an oven, an open box containing adeodorizing and sweetening compound, substantially as specified.

2. In combination with an oven, an open box, having suitable filling and discharging pipes with removable caps and means to show the height of liquid in the said box, substantially as specified.

3. The method of sweetening bread while the same is being baked, herein as described, which consists in bringing a deodorizing and gas neutralizing vapor in contact with the bread, substantially as specified.

MATTHIAS ZOELLER.
